Summary: | Many surgical procedures are available for treating trapeziometacarpal (TMC) osteoarthritis (OA). The aim of this study was to analyze the mid- to long-term outcomes of 103 pyrocarbon interposition arthroplasties in the TMC joint with Pyrocardan® implant performed prospectively in a single center to treat painful early stage OA. There were 96 patients with a median age of 59 years. Twenty-eight percent of patients were manual workers and 39% had a fixed dislocation of the first metacarpal. Fifteen percent of patients were 50 years old or more. After a minimum follow-up of 5 years, there was a marked improvement in the pain level (0.6/10), QuickDASH (9/100) and PRWHE (4/100) scores and strength (key pinch 8kg, grip strength 27kg). There were no differences in strength or range of motion compared to the opposite side. Four patients underwent revision surgeries. Two of them were converted to trapeziectomy. The 5-year implant survival rate was 96.2%. Dislocation of the first metacarpal was completely corrected in 80% of cases. Younger patients (≤50 years old) had slightly better outcomes than older ones. Overall satisfaction rate was 96%. Pyrocardan® interposition implant arthroplasty is a reliable alternative to trapeziectomy, total arthroplasty or fusion of the TMC joint especially for young, active patients.
Plusieurs types d’intervention chirurgicale peuvent être proposés dans le traitement de l’arthrose trapézo-métacarpienne (TMC). Le but de cette étude prospective était d’analyser à moyen et long termes les résultats d’une série monocentrique de 103 arthroplasties par interposition de l’implant en pyrocarbone Pyrocardan®. La série comprenait 96 patients d’âge médian 59 ans dont 15 % étaient âgés de moins de 50 ans. Les patients ont été revus entre 60 et 120 mois au recul médian de 67 mois. Parmi eux, 28 % étaient des travailleurs manuels, et 39 % présentaient une subluxation préopératoire permanente de la base du 1er métacarpien. L’amélioration fonctionnelle a été nette sur la douleur, les scores QuickDASH et PRWHE respectivement à 0,6/10, 9/100 et 4/100 ainsi que la force, en moyenne 8kg pour la pince tripode et 27kg pour la poigne. Les mobilités et la force étaient symétriques au côté opposé. Il y a eu 4 réinterventions dont 2 pour une conversion en trapézectomie. Le taux de survie était de 96,2 %. La subluxation métacarpienne a été corrigée dans 80 % des cas. Les patients de 50 ans ou moins ont eu globalement de meilleurs résultats fonctionnels que le |
